摘要
面对我国大城市所提供各类设施规模难以同时满足3亿农民落户的现实困境,广大县域成为新型城镇化的主要出路。本文希望通过引导区域资源要素流动带动县域城镇发展,提升县域城镇化的空间承载能力,最终实现以“要素流”促进“人口留”的新型城镇化目标。通过架构“以流促留”的理论框架,使用世界500强企业数据与手机信令数据识别资本、人员等要素流动,结合“大数据+问卷调查”分析方法,采用“宏观约束+个体决策”解析机制,分析了长三角县域城镇的空间类型、作用机制与空间模式。研究发现,第一,长三角县域城镇存在“网络化”与“中心流”两种典型模式,其中“网络化模式”更接近实现以“流”促“留”的本地城镇化目标;第二,两种典型模式的作用机制不同,“网络化模式”是产业分工驱动下的县镇内外要素均衡流动,“中心流模式”是住房与社会保障综合作用下县城主导要素流动。第三,从城镇化路径、空间载体、规模借用、空间治理等方面提出实现以“流”促“留”的规划策略。
Faced with the reality that facilities provided by China’s large cities can hardly meet the needs of 300 million farmers settling down,counties have become a focus of new urbanization.This paper aims to drive the development of county towns and enhance their spatial carrying capacity through guiding the flow of regional resource elements,and ultimately achieve the goal of new urbanization–promoting“population staying”through“elements flowing”.The paper analyzes the spatial types,functional mechanisms,and spatial patterns of county towns in the Yangtze River Delta region by developing a theoretical framework of“promoting‘staying’through‘flowing’”,using the Fortune 500 companies’data and mobile signaling data to identify the flow of elements like capital and population,adopting the analysis methods of“big data and questionnaire survey”,and using the analytical mechanism of“macro constraints and individual decision-making”.The findings reveal that,firstly,county towns in the Yangtze River Delta exhibit two typical development patterns:“networking”and“central flowing”.Among them,the“networking”pattern is more likely to achieve the goal of promoting“staying”through“flowing”.Secondly,the two typical patterns differ in the mechanisms.The“networking”pattern refers to the balanced flowing of elements inside and outside counties and towns driven by industrial division of labors,while the“central flowing”pattern refers to the flowing of dominant elements in county town under the comprehensive effect of housing and social security.Thirdly,it proposes planning strategies for promoting“staying”through“flowing”from the aspects of urbanization path,spatial carrier,scale borrowing,and spatial governance.
